VEHICLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 719,179, dated January27, 1903.

Application tiled July 3, 1902. Serial No. 114,180. (No motlelf- To allwhen?, t may concern:

Be it known that l, FRANK P. BRINING, a citizen ofthe United States,residing at Westgrove, county of Chest-er, and State of Pennsylvania,have invented a certain new and useful Improvement in Vehicle-Tires, ot'which the following is a specification.

My invention relates to a new and useful improvemcnt in vehicle-tires,and has for its object to provide a vehicle-tire which will not dependupon the pneumatic tire for its resiliency, but will at the same timehave all the resiliency and advantages of the pneumatic tire without thedisadvantages attendant thereto; and a further object of iny inventionis to provide for the easy insertion and removal of the tire to and fromthe felly and providing at certain intervals retaining devices whichabsolutely prevent the tire from displacement under any and allcircumstances, but provide for its easy and quick removal when desired.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring totheaccompanying drawings, forming a part of this specification, in whiclrmFigure l is a vertical cross-section of the tire and felly; Fig. 2, alongitudinal section of a portion of the tire and felly.

This invention is intended as an improvement over a patent allowed meMarch 8, 1902, on vehicle-tires, Serial No. 93,992, and the tire andfelly of this my present application are practically the same as in theformer one but in this application I have included retaining deviceswhich are located at intervals around the felly for the purpose ofpreventing the displacement of the tire from the felly should the tirebe subjected to any unusual side strain, such as going around curves,dsc.

A represents the felly of the wheel, which has the annular groove Bformed therein, in which is cemented or secured in any suitable manner aring of comparatively soft rubber C. The walls of the groove B aregrooved and undercut at D, as shown in Fig. l.

E is a tire which consists of a solid ring of rubber having a circularopening F formed therethrough, and this tire is split from the opening Fto its edge, as illustrated at G, and has formed therewith the'tonguesII, which are adapted to fit in the undercut groove I) of. the felly.The soft-rubber ring C is beveled at C' upon its outer edge, and theinner face of`the tire E is beveled to correspond upon each side of theslit G. Thus when it is desired to insert the tire in the felly thetongues or beveled edges II upon the tire are pressed or sprung withinthe undercut grooves D of the telly, and the expansion of the rubbertire E, together with the wedging expansion of the soft rubber C, Willtend to hold the tire in place upon the telly, and when the weight ofthe rider or vehicle is upon the tire the tendency of the wedge-face ot'the ring C will be to cause the two portions of the tire upon each sideof the slit G to spread and to be more closely held Within the undercutgroove D of the felly, so that the heavier the weight placed upon thevehicle the more tendency the tire has to hold itself in conjunctionwith the telly, and at the same time the soft-rubber ring C, the openingF, and slit G will give to the tire a great resiliency equal to thepneumatic tire.

Although the tire as just described would when used on bicycles or otherlight vehicles probably be retained in place and never be come displacedfrom the felly, said tires might when attached to heavy vehicles'or whendesigned Vfor fast traveling become det-ached from the telly whensubjected to an unusual side strain, such as when the vehicle is turninga sharp curve. Therefore to provide against any such liability I providethe screw-hook I, which is composed of tWo portions, a male and female.The male portion is provided with a squared outer end J for the purposeof providing a Wrench-hold, and the outer end of the male portion insideof the squared end .I is cylindrical and exteriorly threaded, asindicated at J', and passes through an opening provided through thefelly and is threaded in a nut K, embedded in a recess extendingdownward from the groove B of the felly.

This male portion is reduced upon its extreme inner end and isexteriorly threaded, as illustrated at L, and is threaded into thefemale portion represented by the interiorly-threaded hook M, which hookpasses through an opening provided through the ring C and lies withinthe slit Gr of the tire E and is adapted to hook overa transverse pin N,embedded in the tire. This pin may either be 'vulcanized in the tire ormay be inserted in the tire after it is made by spreading the tire andplacing the sharp-pointed pin against the 'walls of the slit G. Then byforcing the tire to its normal position the pin will enter the tire uponeach side of the slit. These retaining devices are arranged at intervalsaround the Wheel and are secured to the tire in the following manner:The hook is unscrewed from the screw-threaded end L a sufficientdistance so that when it is inserted through the opening formed throughthe felly and also ihrough the ring C the pin N will be opposite thethroat M of the hook, and then by pressing the pin into the hook andthreading the male portion both into the nut II and into the hook M thehook will be drawn toward the felly, and thus bind the tire by means ofthe pin to the felly, so as to prevent absolutely displacement of thetire. For the purpose of preventing any movement of the retaining devicerelative to the felly after the retaining device has been properlyadjusted a jamnnt L is threaded upon the protruding end of the threadedportion J and screwed tight against the inner surface of the felly oragainst the washer interposed between the nut and the felly, so as tobind the retaining device securely against any movement, the

pin N working freely within the hook as the tire is compressed orallowed to expand.

Of course I do not wish to be limited to the exact construction hereshown, as slight modifications could be made without departing from thespirit of my invention.

Having thus fully described myinvention, what I claim as new and usefulis- 1. A fellyhaving an annular groove formed in the same, a ring ofsoft rubber secured within said groove, undercut grooves formed in thewalls of the groove, a rubber tire, beveled edges or tongues formed uponthe tire adapted to fit Within the undercut grooves, an opening formedthrough the tire, a slit fortified from the opening to the inward faceof the tire, pins arranged at intervals in the tire and extendinglaterally across the slit, hooks extending through the felly and alsothrough the soft-rubber ring adapted to be hooked upon said pins, meansfor drawing said hooks toward the felly for the purpose of binding thetire to the felly, as and for the purpose specied.

2. In a Vehicle-wheel tire, a felly, a rubber ring clenched within saidfelly, an opening formedthrough the tire, a slit formed from the openinglo the inner face of the tire, pins arranged within the tire andextending trans versely across the slit, hooks consisting of two parts,a male and female, the male part extending through the felly andthreaded into the female part, a nut threaded upon the male part outsideof the felly, a hook formed upon the female part adapted to hook overthe pin, as and for the purpose specified.

3. In a device of the character described, a felly, a rubber tirecarried by said felly, pins arranged within the tire, retaining deviceseach consisting of two parts, a male and female, the male part extendingthrough the felly and threaded into the female part, .a nut threadedupon the male part outside of the felly, and a hook formed upon thefemale part adapted to hook over the pin in the tire, as and for thepurpose specied.

4L. In combination with a tire and felly of the character described,pins arranged at intervals in the tire and extending trans- Verselyofthe same,tireretaining devices each consisting of two parts, a male andfemale, the male part extending through the felly, a nut embedded in thefelly in which the male part is threaded, a reduced portion formed uponthermale part threaded into the female part, a lock-nut threaded uponthe male part upon the outside of the felly, and a female part providedwith a hook adapted to hook over the pin in the tire, as and for thepurpose specified.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

FRANK P. BRINING.
